Hydromechanical Grease Trap Installation in Flagstaff
Hydromechanical grease traps sit under or near sinks and use baffles and flow control to separate grease from water. They are common in small cafes, coffee shops and quick-service restaurants with limited space. We install units from Zurn, Watts, Schier and Endura sized by gallons per minute. Each install includes a flow control fitting and proper venting to keep the trap working as designed. These units need frequent cleaning, so we place them where staff can reach the lid easily.

In-Ground Gravity Interceptor Installation in Flagstaff, AZ
Larger restaurants and high-volume kitchens often need an outdoor gravity interceptor. These concrete or polyethylene tanks typically range from several hundred to over 1,500 gallons. We excavate, set the tank on a stable base, connect inlet and outlet piping and install manhole risers. Caliche and rocky soil are common in the region, so we plan excavation equipment accordingly. A properly installed interceptor can go much longer between pump-outs than an indoor trap.
New Restaurant Build-Out Grease Traps in Flagstaff
If you are opening a new restaurant, the grease trap is often a key part of plan review. We work with your architect or contractor to size the unit and show it on plumbing plans. We then install it during rough-in so it is ready for inspection. Getting the trap right early avoids costly changes after the slab is poured. We also coordinate with the city's pretreatment staff when they require a review.
Grease Trap Replacement and Upgrades in Flagstaff, AZ
Older traps can rust through, crack or simply be too small for your current menu. We remove failing units and install modern replacements that meet today's code. If your business has grown, we may recommend upgrading to a larger hydromechanical unit or an outdoor interceptor. We review your cleaning records and any violation notices to guide the decision. An upgrade often reduces pumping frequency and lowers long-term costs.
Automatic Grease Removal Units in Flagstaff
Automatic grease removal devices skim grease from the water and collect it in a container your staff empties. Brands like Thermaco Big Dipper are popular in kitchens with limited space and frequent cleaning needs. We install these units with the correct power supply and drain connections. They can reduce the need for frequent pump-outs in smaller kitchens. We explain daily maintenance so your staff keeps the unit running well.
Food Truck Commissary and Ghost Kitchen Traps in Flagstaff, AZ
Commissary kitchens and ghost kitchens often have several prep stations and heavy dishwashing loads. We design grease trap installs that handle high flow from multiple sinks and dish machines. Each unit is sized for the combined discharge, not just one fixture. We also install cleanouts and sample ports where the city requires them. This keeps shared kitchens compliant for every tenant.
Grease Trap Installation for Schools and Institutions in Flagstaff
School cafeterias, hospitals, senior living facilities and churches with kitchens often need commercial interceptors. These sites usually have large dish machines and steam kettles that push high flow. We size interceptors to handle peak lunch or dinner loads without bypassing grease. Our crews schedule work around school breaks or off hours. We also provide documentation for facility managers and inspectors.

Grease Trap Installation Cost in Flagstaff, AZ
Small under-sink hydromechanical traps generally cost much less to install than large outdoor interceptors. Indoor units are typically a few thousand dollars installed, while in-ground interceptors can run well into five figures with excavation and concrete work. Pricing depends on unit size, location, soil conditions and whether we need to cut and patch floors. We give you a written estimate that includes permits and inspection. That way there are no surprises during construction.

Frequently Asked Questions About Grease Trap Installation in Flagstaff
Small indoor hydromechanical traps typically cost $1,500 to $5,000 installed. Large outdoor gravity interceptors often run $8,000 to $30,000 or more with excavation, concrete and site restoration. We provide a written estimate after a site visit.
We calculate flow from every connected fixture, including sinks, floor sinks and dish machines. Hydromechanical units are typically rated by gallons per minute, while gravity interceptors are sized by volume and retention time.
Most food service businesses that cook, wash dishes or prepare food with fats, oils or grease are required to have one. Local pretreatment programs set the specific rules, and we can help you confirm what applies to your site.
Manufacturer warranties vary, with many polyethylene units carrying long structural warranties. We also warranty our installation workmanship and connections.
Yes, commercial grease trap and interceptor installations generally require a plumbing permit and inspection. Some cities also require approval from their pretreatment or wastewater department.
Indoor traps should be close to the fixtures they serve and easy to open for cleaning. Outdoor interceptors are typically placed where a pump truck can reach them without blocking customer traffic.
Commercial grease traps should be installed by a licensed plumber because they require permits, correct sizing, venting and inspection. A DIY install that fails inspection can delay your opening and lead to fines.
That depends on local rules and the trap type. Some programs require dish machines to discharge through the interceptor, while others restrict high-temperature discharge into certain units, so we confirm the requirement before installation.
